Although silicon (Si) is ubiquitous in the earth's crust, its essentiality for growth of higher plants is still under discussion. By recognising the overwhelming potential of Si in alleviating a wide range of biotic and abiotic stresses, the Association of American Plant Food Control Officials and the International Plant Nutrition Institute, Georgia, USA, have designated Si as a plant 'beneficial substance' in 2014 and 2015, respectively. Sugarcane is a Si-accumulating crop which strongly responds to Si fertilisation especially in Si-deficient soil. Due to intensive weathering prevailing in humid and sub-humid regions, most of the soil-available Si, taken up by plants in the form of monosilicic acid (H 4 SiO 4), is lost through leaching. If the concentration of monosilicic acid is being maintained at a fixed level by soil reserves, the highly weathered soils of humid and sub-humid regions tend to become depleted in Si if continuously cultivated with sugarcane. Hence, leaching of Si from the soil coupled with plant uptake is an important factor in determining Si concentrations in soil. Consequently, it can be said that the intensive cultivation of sugarcane depletes the existing low available Si content in soil, resulting in necessity for Si fertilisation. Moreover, the uptake of Si by sugarcane (500-700 kg Si ha −1) sometimes surpasses those of the macronutrients (especially N, P and K). At the same time, due to change in global climate and monoculture system followed in sugarcane, it is affected by a wide range of biotic and abiotic stresses in field condition which calls for external Si supplementation to achieve sustainable growth and yield of sugarcane. The beneficial effects of Si in sugarcane include improvement of photosynthesis and lodging, enhancement of growth and development, regulation of reactive oxygen species, protection from soil salinity, reduction in metal toxicity, alleviation of freeze damage, mitigation of water stress and suppression of diseases and pests. In this review, we made an effort to compile the existing literature describing the potential of Si in promoting defence against various biotic and abiotic stresses in sugarcane and suggested possible future research perspectives.

“…Several Si sources varying in total Si contents and solubility are used in Brazil. Most studies use calcium silicate (CaSiO 3 ) and slags (Camargo et al, 2017;Liang et al, 2015), and only a few studies tested diatomites as a Si source to crops (Nascimento et al, 2020). Diatomite is a sedimentary rock formed by the accumulation of diatom algal fossils and composed predominantly of amorphous silica (SiO 2 .nH 2 O) (Sandhya & Prakash, 2019).…”

Silicon (Si) plays an important role in sugarcane, but there is a gap of information regarding the potential of diatomite as a Si fertilizer to this crop. Here, we assessed the effects of five rates (equivalents to 75; 150; 225; 300 and 375 kg ha-1 Si) of a diatomite-based fertilizer on the biomass yield and concentration of nutrients and Si in sugarcane plants grown on a sandy soil. The efficiency of the extractants acetic acid and calcium chloride in predicting Si uptake was also assessed. Results showed that diatomite was efficient in supplying available Si in the soil and increased Si concentration in the plant. The addition of diatomite significantly increased the available contents of P, K, Mn, Cu, and the cationic exchangeable capacity of the soil. The concentrations of N, P, Mn, Cu, and Zn in shoots were elevated, suggesting that the fertilizer can play a role in the efficient use of nutrients by sugarcane. The extractant 0.01 mol L-1 CaCl 2 was better correlated with Si concentration in plants than 0.5 mol L-1 acetic acid. Therefore, CaCl 2 is the recommended extractant to estimate Si availability because of its higher efficiency and lower cost.

“…Water-deficit-tolerant cultivars present greater a stomatal control and photosynthesis rate than those of sensitive genotypes (Graça et al, 2010). In addition, cropping techniques can be associated with irrigation deficit depths to minimize the effect of water deficit (for example, fertilization with silicon) (Camargo et al, 2017).…”

Irrigation systems with high water application uniformity, adapted cultivars, and management of regulated deficit irrigation (RDI) are some ways to increase water use efficiency in agriculture. RDI is a practice that aims to provide a smaller amount of water than that consumed by crops without significantly affecting agricultural yield. Objectives of this study were to evaluate the technological characteristics (Bx, Juice POL, Fiber, TRS and Cane POL), water use efficiency (WUE), number of stalks, and sugar and stalk yield of five sugarcane cultivars subjected to RDI and non-irrigation. The experiment was conducted at the School of Agricultural and Veterinatian Sciences, São Paulo State, Brazil. The treatments were distributed in a partially balanced incomplete-block design. The RDI provided 50% of the evapotranspiration water by the crop. At each 30 mm water deficit a 15 mm depth was applied. The evaluated sugarcane cultivars were ‘CTC 4’, ‘IACSP 93-3046’, ‘RB 86-7515’, ‘IACSP 95-5000’, and ‘IAC 91-1099’. The total irrigation depth applied during the cycle was 180 mm. The RDI reduced the technological characteristics of sugarcane. However, it increased the productivity of the stalks and sugar, and did not change the number of stalks per hectare, nor the water use efficiency. Among the cultivars, ‘IAC91-1099’ showed the highest sugar yield (21.81 t ha-1), stalk yield (146.5 t ha-1), and water use efficiency (146.7 kg ha-1 mm-1). The cultivar ‘CTC4’ showed little responsiveness to RDI, presenting a lower number of stalks per hectare and water use efficiency in relation to its growth under non-irrigation conditions.
